Just after midnight this morning, a mysterious shark corpse was found laying on the floor of a New York City subway train, with no witnesses or explanation as to how it got there. According to Gothamist, the shark seems to bear some resemblance to the baby sharks once sold in buckets on the subway last year, while some tin foil hatters speculate that this may have been some kind of bizarre viral marketing gimmick for Discovery channel's "Shark Week" series, which began on Sunday.
